Possible autolearn states

In SpamAssassin 2.5 and 2.6, there were only three states for the autolearn result:

• ham: the message was learned as ham (non-spam)
• spam: the message was learned as spam
• no: the message was not learned

In SpamAssassin 3.0, the result was enhanced to have six states:

• ham: the message was learned as ham (non-spam)
• spam: the message was learned as spam
• no: the specific message didn't achieve the proper threshold values and requirements to be learned
• disabled: the configuration specifies bayes_auto_learn 0 or use_bayes 0 and so no autolearning is attempted
• failed: autolearning was attempted, but couldn't complete. This happens if SpamAssassin can't gain a lock on the Bayes database files, etc.
• unavailable: autolearning not completed for any reason not covered above. It could be the message was already learned.
